The Balikpapan class LCH (Landing Craft, Heavy) are a class of eight vessels operated by the Australian Defence Force and the Papua New Guinea Defence Force (PNGDF). They were initially built for the Australian Army, but operational responsibility was transferred from the Army to the Royal Australian Navy (RAN) during 1973 and 1974. Two vessels were transferred to Papua New Guinea after the nation's independence. As of 2012, the three remaining RAN vessels were operational, while the two PNG ships were awaiting refits.

Design and capabilities[edit]

Eight new heavy landing craft were ordered in 1969 as a locally-manufactured replacement for the Australian Army's four LSM-1 class landing ship medium and two ALC 50 landing craft after the Landing Ship Medium Mk II project was cancelled.[1] They are 44.5 metres (146 ft) long, with a beam of 10.1 metres (33 ft), and a draught of 2 metres (6 ft 7 in).[2] The landing craft have a standard displacement of 320 tons, with a full load displacement of 517 tons.[2] They were originally built with two General Motors Detroit 6–71 diesel motors.[3] These were replaced by Caterpillar 3406E diesel engines between 2005 and 2007 for those still in Australian service.[2] The standard ship's company is 16-strong, including two officers.[2] The sensor suite is limited to a Racel Decca Bridgemaster I-band navigational radar.[2] They are fitted with two 7.62 millimetres (0.300 in) machine guns for self-defence.[3]

The LCHs have a maximum payload of 180 tons; equivalent to three Leopard 1 or two M1A1 Abrams tanks, 13 M113 armored personnel carriers, 23 quarter-tonne trucks, or four LARC-V amphibious cargo vehicles.[3][4][5] As a troop transport, a Balikpapan class vessel can transport up to 400 soldiers between a larger amphibious ship and the shore,[citation needed] or embark 60 soldiers[citation needed] in six-berth caravans for longer voyages.[4] The vessel's payload affects the range: at 175 tons of cargo, each vessel has a range of 1,300 nautical miles (2,400 km; 1,500 mi), which increases to 2,280 nautical miles (4,220 km; 2,620 mi) with a 150-ton payload, and 3,000 nautical miles (5,600 km; 3,500 mi) when unladen.[3] The flat, box-like keel causes the ships to roll considerably in other-than-calm conditions, limiting their ability to make long voyages.[4] The LCHs can mate their bow ramp to the stern loading dock of the RAN's large amphibious warfare ships when operating in the ship-to-shore role.[citation needed]

All eight Balikpapan class vessels were constructed by Walkers Limited at their shipyard in Maryborough, Queensland.[6] All were laid down during 1971 and 1972, with lead ship Balikpapan entering service with the Australian Army Water Transport Squadron at the end of 1971.[6] After this, responsibility for seagoing Army craft was transferred to the RAN, with the other seven craft directly entering naval service during 1973 and 1974, and Balikpapan transferring over in late 1974.[6][7]

Operational history[edit]

In January 1973, the Balikpapans in RAN service were formed together as the First Australian Landing Craft Squadron, based at HMAS Moreton in Brisbane.[4]

In November 1974, Salamaua and Buna were transferred to the fledgling Papua New Guinea Defence Force, along with five Attack class patrol boats.[4][8] Five of the remaining Australian LCHs were deployed in December 1974 following Cyclone Tracy as part of Operation Navy Help Darwin; HMAS Labuan was undergoing refits at the time.[9]

HMAS Labuan was assigned to the Royal Australian Navy Reserve in June 1979, and attached to the Brisbane Port Division.[4] Three LCHs, Tarakan, Balikpapan, and Wewak were placed in reserve at NQEA in Cairns during August and September 1985.[4] They were reactivated in 1988, 1990, and 2000, respectively.[3]

On entering service, Brunei and Betano initially supplemented the inshore hydrographic survey capabilities of the RAN until late 1988, when they were reassigned to the naval base HMAS Waterhen for use in diver training.[3]

During May and June 1984, Balikpapan completed a 5,400-nautical-mile (10,000 km; 6,200 mi) transit from Brisbane to Penang, transporting vehicles, equipment, and personnel to RAAF Butterworth; the longest ocean voyage undertaken by a vessel of this class.[9]

During 1985 and 1986, Salamaua and Buna underwent refits.[10]

Between 1997 and 2003, the LCHs were used to support the Peace Monitoring Group (PMG) in Bougainville, under Operation Bel Isi.[11] Ships deployed on this operation were involved in resupplying the PMG base in Loloho, transport of PMG personnel and humanitarian aid, and coastal patrols.[11] From 1999 onwards, the Balikpapans were also tasked with supporting INTERFET operations in East Timor, particularly those relating to the Oecussi enclave.[11] The increase in operational tempo was a major factor in the reactivation of Wewak in 2000.[11] In 2003, the landing craft began supporting RAMSI operations in the Solomon Islands.[11]

As of 2013, three Australian vessels are active; two based at HMAS Cairns in Cairns, Queensland, with the other at HMAS Coonawarra in Darwin, Northern Territory.[5] The two PNG vessels have been listed in Jane's Fighting Ships as non-operational since 2011, although they are awaiting refits to restore them to service.[12]

Decommissioning and fates[edit]

On 11 December 2012, Wewak was decommissioned.[13] Balikpapan and Betano were both decommissioned a day later, on 12 December.[14][15][16] The other three Australian vessels will decommission during 2014, with the entire class to be replaced by an as-yet-unidentified class of six heavy landing craft.[13][17] The original replacement project was not due to decide on the design until between 2016 and 2018, with the new class to enter service from 2022.[5] The Department of Defence issued a request for information in early 2011, which may lead to the project being brought forward.[5]
